How can we improve Azure Networking?

Provide certificate-based authentication for S2S VPN

Can you describe the technical reason why you decide not to offer this option when creating a s2s vpn and you offer only the phase1 pre-shared key method? The communications in Madrid HC Region are administered by Cesus and they follow directives from the Security Group of Madrid Digital (former ICM). In their form to require a s2s vpn only cert based is accepted for ipsec tunnels and without a clear technical reason it is almost impossible to negotiate an exception to shift to pre-shared key based phase 1 vpn

Thank you for the suggestion. The key reasons for not offering cert-based IKE authentication is due to the additional compliance requirements and validations related to handling certificates. As a result, this is currently not on the roadmap.

If certificate-based authentication is a requirement, currently customers will need to leverage a VPN appliances available from Azure Marketplace.
